Title

Initiation and Elongation of Lateral Roots inLactuca sativa

Nenggang Zhang; Karl H. Hasenstein International Journal of Plant Sciences 1999. doi:10.1086/314147

Other claims from this paper (15)

Intervention effect Removal of the root tip triggered lateral root formation in seedlings that do not normally produce lateral roots.
Intervention effect Application of auxin, especially indole-butyric acid, triggered lateral root formation.
Observation Primordia were initiated within 9 h.
Observation Primordia were fully developed after 24 h.
Mechanism The authors propose that primordia form by activation of pericycle cells opposite the xylem pole.
Observation Pericycle cells divided asymmetrically into short and long cells.
Observation The short cells divided further to form primordia.
Intervention effect The effect of root-tip removal and auxin application on lateral roots was reversed by 6-benzylaminopurine.
Intervention effect The cytokinin oxidase inhibitor N1-(2chloro4pyridyl)-N2-phenylurea suppressed auxin-induced lateral rooting.
Intervention effect L-alpha-(2-aminoethoxyvinyl) glycine promoted primary root elongation.
Intervention effect Silver ions promoted primary root elongation.
Intervention effect Silver ions enhanced lateral root elongation.
Intervention effect L-alpha-(2-aminoethoxyvinyl) glycine did not enhance lateral root elongation.
Mechanism Lateral root induction is controlled by basipetally moving cytokinin.
Mechanism Lateral root induction is controlled by acropetally moving auxin.

Developmental effects of 24‐epibrassinolide in excised roots of tomato grown in vitro

James G. Roddick; Anna L. Rijnenberg; Nobuo Ikekawa Physiologia Plantarum 1993. doi:10.1111/j.1399-3054.1993.tb02493.x

Other claims from this paper (6)

Intervention effect Epibrassinolide inhibited root growth only at 0. 1 μ M or above.
Intervention effect At 10 μ M, basal and apical application inhibited growth in apical regions, but not basal regions.
Intervention effect At 1 μ M, epibrassinolide inhibited apical region growth, usually with direct presentation.
Intervention effect At 0. 1 μ M, epibrassinolide inhibited apical region growth, usually with direct presentation.
Mechanism Authors attribute reduced epibrassinolide responsiveness to larger inoculum.
Association Cultured root sensitivity to epibrassinolide may be directly related to growth rate.

(376) Carbon Mobilization and Yield Components in Raspberry

Horacio E. Alvarado; Rebecca L. Darnell; Jeffrey G. Williamson HortScience 2005. doi:10.21273/hortsci.40.4.1059d

Other claims from this paper (9)

Intervention effect Girdling and absence of primocanes decreased fruit number and yield relative to nongirdled plants with primocanes.
Intervention effect Individual fruit fresh weight was not affected by treatments.
Intervention effect Fruit dry weight and dry-to-fresh weight ratio were higher in girdled plants without primocanes.
Intervention effect Girdling and primocane presence did not affect dry weight allocation to canes.
Intervention effect Root dry weight was higher with girdling and primocanes than without both.
Mechanism Primocanes appear to supply carbon to roots during fruiting.
Mechanism Roots appear to provide a carbon translocation pathway from primocanes to floricanes.
Mechanism Suppressed primocane growth appears to mobilize root carbon for floricane development.
Intervention effect Restricted root-to-floricane carbon flow significantly decreases fruit number and yield.

Carbohydrate production in guayule

K.M. Kelly; J. van Staden South African Journal of Botany 1994. doi:10.1016/s0254-6299(16)30612-3

Other claims from this paper (10)

Observation Guayule produces ethanol-soluble and water-soluble fructans.
Observation Water-soluble fructans serve as a carbohydrate reserve.
Association Water-soluble fructans depolymerize readily when carbon demand rises greatly.
Observation Ethanol-soluble fructans are rapidly metabolized as an accessible carbohydrate source.
Observation Ethanol-soluble fructans depolymerize extensively at budbreak and flowering.
Observation Water-soluble fructans polymerize in November/December and during winter.
Mechanism The winter polymerization pattern indicates excess fructose availability.
Observation Root fructan stores appear least accessible.
Observation Starch occurs primarily in leaves.
Mechanism Starch is apparently involved in sucrose storage.

The Relation Between Age of Stem Tissue and the Capacity to Form Roots

P.W. Zimmerman; A.E. Hitchcock Journal of Gerontology 1946. doi:10.1093/geronj/1.1_part_1.27

Other claims from this paper (7)

Association Plant tissue age relates to natural adventitious rooting capacity.
Observation Lilac cuttings taken in May can form adventitious roots.
Association Lilac cuttings gradually lose rooting capacity by July.
Intervention effect Apple cuttings taken early in May rooted with growth substances but their capacity declined until June.
Observation Seedling cuttings of difficult species can root.
Observation Cuttings from old trees seldom root even with hormone-like substances.
Mechanism Age-associated structural or protoplasmic change is proposed as a major rooting control.
